They saved the best mission for last. Before passing off the baton to the next generation, the original crew of the Starship Enterprise has one more voyage to undertake. This time it is to broker peace between the Federation and the Klingon Empire. When Captain Kirk is framed for murder, that fragile peace is upended. Spock races to catch the real killer and rescue Kirk and McCoy from a frozen penal colony. It all culminates with a suspenseful outer-space shoot-out. William Shatner, Leonard Nimoy and DeForest Kelly co-star with the rest of the original cast in this terrific entry in the sci-fi saga.
